Comment 6 for bug 1849787

I have the same issue. It forced me to revert back to 19.04 from latest ver. of 19.10.

It was already a problem since week prior to release of 19.10 (when I first tried).

19.10 latest ver on Intel Graphics 530.
This bug is impacting on: modesetting driver xorg as well as intel driver xorg. I also tried Wayland to same result.

This is impacting a fullscreen video game I'm playing in OpenGL.
